Definitions

  • the invention relates to a vehicle lamp with a plurality of on one Carrier plate arranged LEDs, with a plurality of in the direction of light propagation reflectors arranged downstream of the respective light-emitting diodes Deflecting the light in the direction of a housing front side of a housing, so that the light in a given light exit direction from the Housing emerges, the light exit direction inclined to the optical Axis of the LEDs is oriented.
  • a vehicle lamp in which both Light-emitting diodes and reflectors corresponding to these in rows are arranged.
  • the reflectors serve to redirect that from the respective LEDs emitted light in the direction of a front of the vehicle lamp, on which a lens with optical elements is arranged is.
  • the lens is essentially perpendicular to the light exit direction oriented.
  • the optical axis of the light emitting diodes are inclined to the light exit direction and in the direction of the corresponding reflectors oriented so that a large part of the luminous flux is captured by the reflectors and can be redirected accordingly.
  • DE 196 47 094 A1 describes a vehicle lamp with a plurality of a strip-shaped carrier plate arranged LEDs known the light emitted by the respective light emitting diodes through a reflector is deflected and guided towards a lens.
  • An optical axis the light-emitting diode is inclined to the light exit direction specified by the reflector educated. Due to the inclined arrangement of the light emitting diode in cooperation with the reflector, the space required for the vehicle lamp be reduced.
  • a disadvantage of the known vehicle lamp is, however, that only due to the row-shaped arrangement of the LEDs a limited luminous flux can be generated.
  • the object of the present invention is to develop a vehicle lamp in such a way that that the efficiency is improved with a shallow depth.
  • the invention is in connection with the preamble of claim 1, characterized in that the reflectors to a Reflector unit are combined with a base level from which the reflectors extend in terraces.
  • the invention enables by providing a terraced arranged reflectors existing reflector unit a compact Vehicle lamp that also meets the requirements for the vehicle lamp in from a lighting and aesthetic point of view.
  • Basic idea of the invention is to arrange the reflector unit in steps or steps so that the light-emitting diodes in a conventional, simple manner on corresponding carrier plates can be arranged contacted.
  • the invention extend in one Row of reflectors arranged in steps, increasing the distance to a base level in the direction of a housing front, so that the LEDs on a common carrier plate that runs in the base plane, can be arranged.
  • the reflector unit is preferably in one piece formed so that only two units, namely the reflector unit on the one hand and the carrier plate provided with the light emitting diodes on the other must be aligned with each other.
  • the reflectors extend in a step-like manner increasing the distance to a base plane in the direction a back of the case.
  • the LEDs can be advantageous each positioned at the same distance from the corresponding reflectors so that a homogeneous light emission is guaranteed.
  • Advantageous can the liner strips on the back of an adjacent row are supported by reflectors so that when mounting the carrier strips Tolerance errors can be reduced.
  • the shape of the individual reflectors designed such that a predetermined light distribution is generated.
  • the optically effective contour of the reflector is designed so that a Cover plate arranged on the front of the housing is clear and free can be formed by optical elements.
  • the vehicle lamp according to the invention can be used, for example, as a rear lamp (Brake light or the like) or as one in the upper rear contour area arranged additional brake light of the vehicle.
  • the vehicle lamp essentially consists of a housing 1 in which a plurality of light emitting diodes 2 and a reflector unit 3 are arranged are.
  • the housing 1 has a housing rear and a in the usual way Front of the housing 4, the front of the housing 4 by a crystal clear and cover plate designed free of optical elements (not shown) is covered.
  • Each light emitting diode 2 is a reflector 6 Assigned reflector unit 3.
  • the reflectors 6 are formed uniformly.
  • the optically effective one Surface of the reflector 6 designed such that that of the corresponding Light-emitting diode 2 essentially emitted upwards in the vertical direction Light (vertical light propagation direction 7) not only redirected, but also bundled or scattered according to a predetermined light distribution becomes.
  • the reflector has 6 such a trough-shaped contour that the light rays 8 in cross horizontal and vertical direction.
  • the reflector 6 thus causes a scattering, so that on an additional lens with optical elements can be dispensed with on the front of the housing 4. Leave the light rays 8 the front of the housing 4 essentially in a horizontal Light exit direction 9.
  • the common carrier plate 5 of the light-emitting diodes 2 forms a base plane for the terrace-shaped reflector unit 3. Starting from this horizontal base plane 5, three rows of reflectors extend gradually inclined towards the front of the housing 4. It is located the reflector 6 corresponding to a light emitting diode 2 in Essentially perpendicular over the same. While the LEDs 2 in one If the planes are offset from one another, the reflectors 6 are in one three-dimensional space offset from each other. A front 10 the reflector unit 3 extends essentially from the base plane diagonally forward towards the front of the housing 4.
  • the reflector unit 3 is formed in one piece, the adjacent reflectors 6 lie directly next to each other on the edge.
  • the arrangement consisting of reflector unit 3, support plate 5 and LEDs 2 are also arranged mirrored about a horizontal central plane his.
  • the carrier plate 5 extends in one area an upper housing wall, while a front edge of the Reflector unit 3 runs in the area of the front side 4 of the housing.
  • LEDs 11 arranged in rows on support strips 12.
  • the supporting strips 12 are stepped transversely to the direction of optical axes 13 of the light-emitting diodes 11 arranged.
  • the carrier strips 12 are each on a rear side 14 one arranged adjacent to a row of optically coupled reflectors 15 ' Row of reflectors 15 "on.
  • a reflector unit 16 is provided, which is offset from one another three arranged rows of reflectors 15. Because the LEDs 11 each at the same distance and directly on the edge of the corresponding Reflectors 15 are arranged, the offset of the rows of reflectors 15 formed larger in the light exit direction 9 than after the first Embodiment.
  • the terrace-like Structure of the light emitting diodes 11 a space-saving installation in a housing Vehicle light can be guaranteed because the arrangement is essentially through the shape of the reflector unit 16 is predetermined.
  • the rows of reflectors 15 are stepped from an upper Housing wall in the direction of a lower housing wall with offset towards the back of the case. It can thus be the same beveled Contour the back of the case, which is beneficial to education one on the edge of an essentially horizontal body part of the vehicle is suitable, in particular an edge of a trunk.
  • the reflectors 15 can also be made in one piece be trained.
  • the structure and structure of the reflectors 15 correspond to those of the first embodiment.
  • the reflectors 6 and 15 can also be paraboloidal or ellipsoidal be trained.
  • a corresponding with Optic elements provided cover plate may be provided.
  • the reflectors 6 and 15 can form the rear of the housing 1.
